Herniated discs in the lumbar region cause pain in the feet because the spinal cord and nerve roots in the lower back are irritated and compressed. Foot pain is usually caused by a herniated disc at L4-5 or L5-S1. A herniated disc at L4-5 compressing a nerve root may cause significant pain or numbness in the back of the foot, while a herniated disc at L5-S1 may manifest as pain in the sole of the foot. Treatment depends on the severity of the compression and the presence of obvious symptoms. If the compression is particularly severe and the symptoms seriously affect daily life, surgery is recommended to remove the herniated disc. If the herniated disc is not serious, just a slight bulging or irritation is the main symptom, you can carry on conservative treatment. The lumbar disc herniation foot pain should be timely medical treatment, improve the relevant examination, clear diagnosis, follow the doctor’s instructions for standardized treatment, so as not to delay the condition.
